Resumen
El control cognitivo implica el monitoreo de las acciones y los resultados. La actividad de la corteza frontal medial posterior (pMFC) señala ajustes de rendimiento, interactuando con la corteza prefrontal lateral (LPFC) para el comportamiento adaptativo.
Área de la Ciencia:
- Neurociencia cognitiva y neurociencia cognitiva.
- La neuroimagen es una técnica de neuroimagen.
- Estudios de Primates Estudios de Primates Estudios de Primates Estudios de Primates Estudios de Primates Estudios de Primates Estudios de Primates Estudios de Primates Estudios de Primates Estudios de Primates
Sus antecedentes:
- El comportamiento adaptativo dirigido a objetivos requiere el monitoreo de las acciones y los resultados.
- El control cognitivo facilita los ajustes en el comportamiento y el aprendizaje.
- Comprender las bases neuronales del control cognitivo es crucial.
Objetivo del estudio:
- Evaluar los nuevos hallazgos en neurociencia cognitiva sobre las interacciones corticales para el control cognitivo.
- Identificar las regiones cerebrales involucradas en el monitoreo de acciones y resultados.
- Para dilucidar las interacciones funcionales entre las regiones cerebrales durante los ajustes de rendimiento.
Principales métodos:
- Revisión de estudios en primates y en humanos.
- Metaanálisis de los datos de neuroimagen funcional humana.
- Análisis de focos de activación relacionados con el monitoreo de resultados, errores, conflictos e incertidumbre.
Principales resultados:
- La detección de resultados desfavorables, errores, conflictos e incertidumbre activa regiones superpuestas en la corteza frontal medial posterior (pMFC).
- La actividad de pMFC está directamente relacionada con los ajustes de rendimiento posteriores.
- Se observaron interacciones funcionales entre pMFC y la corteza prefrontal lateral (LPFC), con la señalización de pMFC a LPFC para el control regulatorio.
Conclusiones:
- La corteza frontal medial posterior (pMFC) juega un papel clave en el monitoreo del rendimiento y la señalización de la necesidad de ajustes.
- La corteza prefrontal lateral (LPFC) está involucrada en la implementación de estos ajustes de rendimiento, involucrados por las señales pMFC.
- Estos hallazgos resaltan la importancia de las interacciones pMFC-LPFC para el comportamiento orientado a objetivos adaptativos y el control cognitivo.

01:33Somatosensation
The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.
01:16Sensory Functions of the Skin
The skin is the largest organ of the human body and plays a crucial role in our sensory perception. It contains a vast network of sensory receptors that contribute to the skin's protective function by perceiving physical, biological, and environmental cues and generating relevant responses.
There are two main categories of receptors on the skin: capsulated and non-capsulated. The non-capsulated ones are mainly the pain receptors. The capsulated ones can be further categorized based on the...

01:25Introduction to the Integumentary System
The integumentary system is the organ system that comprises the skin and its associated structures. It is the largest system in the human body and plays a crucial role in protecting and maintaining homeostasis. The integumentary system serves several functions including protection, regulation, sensation, and secretion.
The skin, which is the primary organ of the integumentary system, consists of three main layers: the epidermis, dermis, and hypodermis (subcutaneous tissue). The epidermis is the...

01:11Sensory Perception: Organization of the Somatosensory System
The somatosensory system is the central and peripheral nervous system component that senses and processes touch, pressure, pain, temperature, and body position or proprioception. The process of sensation takes place at three levels:
The receptor level:
The receptor level is the first stage of sensation. It involves the detection of a stimulus by specialized sensory receptors. The stimulus must arrive within the receptor's receptive field. Next, the receptor converts the energy of the stimulus...

01:10Control Systems
Control systems are everywhere in contemporary society, influencing diverse applications from aerospace to automated manufacturing. These systems can be found naturally within biological processes, such as blood sugar regulation and heart rate adjustment in response to stress, as well as in man-made systems like elevators and automated vehicles. A control system is essentially a network of subsystems and processes that collaboratively convert specific inputs into desired outputs.

01:28Perception
Perception is a fundamental psychological process that enables individuals to organize, interpret, and consciously experience sensory information. This process is crucial for understanding and interacting with the world around us. It includes both bottom-up and top-down processing, each playing a distinct role in how we perceive our environment.
Bottom-up processing begins at the sensory level, where receptors detect external environmental stimuli. These could include the tactile sensation of...
